Description

Technical Field

[0001] This utility model relates to a piece of furniture, and more particularly to an armrest mounting structure and a seat. Background Technology

[0002] To improve seating comfort, some seats are equipped with armrests. During manufacturing, some seats have their armrests assembled as a single unit before shipping. However, this type of seat takes up considerable space during transport, increasing costs. Therefore, some seats have their armrests removed from the seat and packaged separately to reduce overall space usage during transport. However, this method requires multiple screws and other connectors to secure the armrests to the seat from different directions before use, making installation somewhat cumbersome. Therefore, there is a pressing need for a structure that facilitates the easy installation and securing of armrests. Utility Model Content

[0003] The purpose of this utility model is to provide an armrest mounting structure and a seat to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A handrail installation structure includes: a connector, comprising a vertical section and a support section connected to the bottom end of the vertical section, the support section extending in a direction away from the vertical section, and sliding grooves respectively provided on both sides of the vertical section; a handrail body, on one side of which at least two slide rails are spaced apart in a horizontal direction, and anti-detachment protrusions are formed on the opposite sides of the two slide rails, the two anti-detachment protrusions respectively engaging with the two sliding grooves; and a locking member connected to the support section and the handrail body.

[0006] This technical solution has at least the following beneficial effects: The connector is used to install onto the seat. Before production, the connector can be fixed to the seat first, while the armrest body and the connector are separate, facilitating overall packaging and transportation. When the user needs to use the seat, the slide rail on the armrest body can be aligned with the slide groove on the connector, and then the anti-detachment protrusion can be slid into the slide groove. Through the cooperation of the anti-detachment protrusion and the slide groove, the armrest body and the connector can be quickly connected and positioned. Since the vertical section and the support section form an L-shaped structure, when the armrest body is connected to the connector, it is positioned by the vertical section... The sliding fit allows for quick connection and positioning of the armrest body, preventing it from detaching from the vertical section in the horizontal direction. The supporting section supports the armrest body and limits its sliding stroke when it engages with the vertical section. Finally, the locking element connects the supporting section and the armrest body, restricting the relative sliding between the armrest body and the connecting element, thus fixing the armrest body in place. In this way, the armrest body can be quickly installed on the seat through the quick pairing and connection of the armrest body and the connecting element. It has a connection and positioning structure for the armrest body in both the vertical and horizontal directions, resulting in a stable connection structure and strong practicality.

[0007] As a further improvement to the above technical solution, the top two sides of the vertical section are inclined from top to bottom in a direction that moves away from each other. The inclined top of the vertical section facilitates the quick and easy insertion of the vertical section into the first groove, thereby improving the overall assembly efficiency.

[0008] As a further improvement to the above technical solution, a first groove is provided on the side of the handrail body facing the connector. The first groove extends downward to the bottom side of the handrail body, and multiple slide rails are respectively disposed in the first groove. The vertical section is located in the first groove. When the handrail body and the vertical section are engaged, the handrail body is slidably engaged with the connector from top to bottom, so that the vertical section enters the first groove. At this time, the slide rails and grooves in the first groove engage with each other to achieve a sliding connection between the handrail body and the vertical section. Furthermore, the vertical section being located in the first groove makes the connection between the vertical section and the handrail body more compact.

[0009] As a further improvement to the above technical solution, the top end of the vertical section abuts against the position of the handrail body located on the top side of the first groove. When the handrail body and the vertical section are slidably connected in place, the top end of the vertical section abuts against the position of the handrail body located on the top side of the first groove, which can limit the sliding stroke of the handrail body at the top position and further enhance the stability of the connection between the handrail body and the vertical section.

[0010] As a further improvement to the above technical solution, a second groove is provided on the bottom side of the handrail body. The second groove extends to the side of the handrail body near the connector, and the supporting section is located within the second groove. When the supporting section is connected to the handrail body, the supporting section enters the second groove on the bottom side of the handrail body. The second groove can be used to accommodate and position the supporting section, making the connection between the handrail body and the supporting section more compact and improving the overall appearance.

[0011] As a further improvement to the above technical solution, mounting holes are provided on the vertical section. When it is necessary to connect and fix the connector to the seat, screws, bolts, or other locking structures can be inserted through the mounting holes, improving the convenience of installing and fixing the connector.

[0012] As a further improvement to the above technical solution, at least two locking members are provided at intervals along the length of the support section. When further locking the support section and the handrail body, multiple locking members can be connected between the two to improve the reliability of the connection and prevent the handrail body from shaking due to the loosening of a single locking member.

[0013] As a further improvement to the above technical solution, the two sliding grooves each include an upper groove and a lower groove spaced apart in the vertical direction. The handrail body is provided with sliding rails corresponding to the positions of the two upper grooves and the two lower grooves. The two anti-detachment protrusions are respectively engaged and connected to the two upper grooves, and the two anti-detachment protrusions are respectively engaged and connected to the two lower grooves. The anti-detachment protrusions are slidably connected to the upper and lower grooves, forming a sliding locking structure at different positions between the handrail body and the vertical section, thereby further improving the stability of the handrail body connection.

[0014] As a further improvement to the above technical solution, the tops of the two lower slide rails are respectively connected to limit blocks. The connecting piece has notches corresponding to the positions of the two limit blocks, and the two limit blocks abut against the connecting piece at the bottom sides of the two notches. When the handrail body and the vertical section are assembled in place, the two limit blocks abut against the connecting piece at the bottom sides of the two notches, restricting the downward movement of the handrail body and providing vertical positioning constraints on the handrail body and the vertical section, further improving the stability of the handrail body connection.

[0015] A seat includes a backrest, the aforementioned armrest mounting structure, and the connector being attached to the backrest.

[0016] This technical solution has at least the following beneficial effects: Since the seat has the above-mentioned armrest installation structure, the connector can be directly installed and fixed on the backrest during production. Before use, the armrest body is connected and fixed to the connector. This not only facilitates the packaging and transportation of the seat, but also enables the armrest body to be quickly installed on the seat through the quick pairing and connection of the armrest body and the connector. Furthermore, the connection structure is stable and highly practical. Attached Figure Description

[0027] Reference Figure 1 , Figure 2 and Figure 3 A handrail installation structure includes a connector 100, a handrail body 200, and a locking member 300. The connector 100 has sliding grooves on both sides. The handrail body 200 has at least two horizontally spaced slide rails 210 on one side. Anti-detachment protrusions 211 are formed on opposite sides of the two slide rails 210. The two anti-detachment protrusions 211 are respectively engaged with the two sliding grooves. After the anti-detachment protrusions 211 and the sliding grooves are engaged, the handrail body 200 can only be separated from the connector 100 along the direction of their sliding connection. The locking member 300 connects the connector 100 and the handrail body 200. Its structural form can be various; for example, the locking member 300 can be a screw, bolt, rivet, etc.

[0028] As described above, the connector 100 is used to install onto the seat. Before production, the connector 100 can be fixed to the seat, while the armrest body 200 and the connector 100 are separate, facilitating overall packaging and transportation. When the user needs to use the seat, the slide rail 210 on the armrest body 200 can be aligned with the slide groove on the connector 100, and then the anti-detachment protrusion 211 can be slid into the slide groove. Through the cooperation between the anti-detachment protrusion 211 and the slide groove, the armrest body 200 and the connector 100 can be quickly connected and positioned. Since the vertical section 120 and the supporting section 130 form an L-shaped structure, when the armrest body 200 is connected to the connector 100, it can achieve [the desired connection / position] through sliding cooperation with the vertical section 120. The quick-connection positioning of the armrest body 200 restricts the armrest body 200 from detaching from the vertical section 120 in the horizontal direction. The supporting section 130 supports the armrest body 200 and restricts the sliding stroke of the armrest body 200 when it cooperates with the vertical section 120. Finally, the locking member 300 is connected to the supporting section 130 and the armrest body 200 to restrict the relative sliding of the armrest body 200 and the connecting member 100, thus connecting and fixing the armrest body 200. In this way, the armrest body 200 can be quickly installed on the seat through the quick pairing connection of the armrest body 200 and the connecting member 100. The armrest body 200 has a connection positioning structure in both the vertical and horizontal directions, the connection structure is stable, and the practicality is strong.

[0029] Naturally, the armrest body 200 can be connected to the L-shaped connector 100. The side of the armrest body 200 near the connector 100 has a first connecting side extending in the same direction as the vertical section 120 and a second connector 100 extending in the same direction as the support section 130. At this time, the first connecting side and the second connecting side are also L-shaped. The top side of the armrest body 200 is used to support the user's hands.

[0030] To facilitate the assembly of the vertical segment 120 into the first groove 220, in this embodiment, the top two sides of the vertical segment 120 are inclined from top to bottom in a direction that moves away from each other. This inclined top arrangement of the vertical segment 120 allows for quick and easy upward insertion and connection to the first groove 220, thereby improving overall assembly efficiency.

[0031] In the above embodiment, after the handrail body 200 and the vertical section 120 are connected to each other, the vertical section 120 can be exposed outside the handrail body 200. However, this will affect the overall appearance. Therefore, in this embodiment, a first groove 220 is provided on the side of the handrail body 200 facing the connector 100. The first groove 220 extends downward to the bottom side of the handrail body 200. A plurality of slide rails 210 are respectively disposed in the first groove 220, and the vertical section 120 is located in the first groove 220. When the handrail body 200 and the vertical section 120 are engaged, the handrail body 200 is slidably engaged with the connector 100 from top to bottom, so that the vertical section 120 enters the first groove 220. At this time, the slide rail 210 and the slide groove in the first groove 220 engage with each other to realize the sliding connection between the handrail body 200 and the vertical section 120. Furthermore, the vertical section 120 is located in the first groove 220, making the connection between the vertical section 120 and the handrail body 200 more compact.

[0032] When the handrail body 200 and the vertical section 120 are fitted together, there may still be a distance between the handrail body 200 and the top side of the first groove 220. Even in this case, the handrail body 200 and the vertical section 120 can still fit together. Since there is movable space between the vertical section 120 and the top side of the first groove 220, the stability of the handrail body 200 is relatively low. Therefore, to further improve the structural stability of the vertical section 120 after it is inserted into the first groove 220, in this embodiment, the top end of the vertical section 120 abuts against the position of the handrail body 200 located on the top side of the first groove 220. When the handrail body 200 and the vertical section 120 are slidably connected in place, the top end of the vertical section 120 abuts against the position of the handrail body 200 located on the top side of the first groove 220. This limits the sliding stroke of the handrail body 200 at the top position and further enhances the stability of the connection between the handrail body 200 and the vertical section 120.

[0033] Furthermore, a second groove 230 is provided on the bottom side of the handrail body 200, extending to the side of the handrail body 200 near the connector 100, and the support section 130 is located within the second groove 230. When the support section 130 is connected to the handrail body 200, the support section 130 enters the second groove 230 on the bottom side of the handrail body 200. The second groove 230 can be used to accommodate and position the support section 130, making the connection between the handrail body 200 and the support section 130 more compact and improving the overall appearance. In practical applications, the vertically extending first groove 220 and the horizontally extending second groove 230 are interconnected. At this time, the first groove 220 and the second groove 230 form a space for accommodating and storing the connector 100, which can easily and tightly fix the connector 100 within the handrail body 200.

[0034] In practical applications, the vertical segment 120 needs to be installed on the seat. There are various ways to install and fix the vertical segment 120, such as fixing it with a snap-fit ​​connection or by using a locking structure such as screws. Therefore, to facilitate the installation and fixation of the vertical segment 120, a connection and positioning structure can be pre-set on the vertical segment 120. Specifically, the vertical segment 120 is provided with mounting holes 121. When it is necessary to connect and fix the connector 100 to the seat, screws, bolts, or other locking structures can be inserted through the mounting holes 121, improving the convenience of installing and fixing the connector 100. In practical applications, there can be multiple mounting holes 121. For example, mounting holes 121 can be provided on the upper, middle, and lower parts of the vertical segment 120.

[0035] In some embodiments, at least two locking members 300 are spaced apart along the length of the support section 130; for example, the number of locking members 300 is two or three. When the support section 130 is further locked to the handrail body 200, multiple locking members 300 can be connected between the two to improve the reliability of the connection and prevent the handrail body 200 from shaking due to the loosening of a single locking member 300.

[0036] The sliding grooves on both sides of the connector 100 can extend along the length of the connector 100 to cover most of the connector 100 or even be the same length as the connector 100. At this time, the slide rail 210 on the handrail body 200 also needs to be set to the same length as the sliding groove. In this way, multiple connection points can be formed between the handrail body 200 and the connector 100 in the vertical direction. In order to save the length of the slide rail 210 and reduce material costs, in this embodiment, the slide rail 210 can be designed as a segmented type. Specifically, the two sliding grooves respectively include an upper groove 111 and a lower groove 112 arranged at intervals in the vertical direction. The handrail body 200 is provided with slide rails 210 at the positions corresponding to the two upper grooves 111 and the two lower grooves 112. The two anti-detachment protrusions 211 are respectively connected to the two upper grooves 111 and the two anti-detachment protrusions 211 are respectively connected to the two lower grooves 112. Thus, two sets of slide rails 210 are formed in the first groove 220. Each set of slide rails 210 has two slide rails 210 arranged side by side at intervals, so that the upper and lower sets of slide rails 210 can be slidably connected to the upper groove 111 and the lower groove 112 respectively. A sliding locking structure can be formed at different positions between the handrail body 200 and the vertical section 120, thereby further improving the stability of the connection of the handrail body 200.

[0037] Furthermore, the top ends of the two lower slide rails 210 are respectively connected to limit blocks 212. The connector 100 is provided with notches 122 corresponding to the positions of the two limit blocks 212. The two limit blocks 212 abut against the bottom sides of the connector 100 at the two notches 122. When the handrail body 200 and the vertical section 120 are assembled in place, the two limit blocks 212 abut against the bottom sides of the two notches 122 on the connector 100, which can restrict the downward movement of the handrail body 200 and provide vertical positional limitation for the handrail body 200 and the vertical section 120 at this position, further improving the stability of the connection between the handrail body 200 and the vertical section 120.

[0038] like Figure 4 As shown, a seat includes a backrest 400 and the aforementioned armrest mounting structure. The connector 100 is connected to the backrest 400. Only the backrest 400 and the aforementioned armrest mounting structure are shown in the figure.

[0039] In this seat, because the seat has the aforementioned armrest mounting structure, the connector 100 can be directly installed and fixed on the backrest 400 during production. Before use, the armrest body 200 is then connected and fixed to the connector 100. This facilitates the packaging and transportation of the seat, and the armrest body 200 can be quickly installed on the seat through the quick pairing connection between the armrest body 200 and the connector 100. The connection structure is also stable and highly practical.

[0040] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
